Improved recovery following posttransplant acute renal failure in rat renal isografts with an oral endothelin-A receptor antagonist.

Delayed renal function after transplantation is a strong predictor of long-term graft survival. As an increased expression of endothelin (ET) has been demonstrated during ischemia/reperfusion injury, we hypothesized that ET-A receptor blockade could improve the recovery of acute renal failure in a rat model of isogeneic kidney transplantation.
